4HP 3kW 4″ Doyin Single-Phase Borehole Pump Motor

The 4HP 3kW 4″ Doyin Single-Phase Borehole Pump Motor is a high-power submersible drive built for demanding deep-borehole installations where three-phase electricity is not available.

Delivering 3kW (4HP) of motor power, it is designed to drive compatible pump bodies used for deep-water extraction, elevated tank filling and demanding agricultural water systems.

Its 4-inch submersible configuration allows it to form part of a correctly matched borehole pump assembly, while the single-phase AC design makes it especially practical for farms, homes and properties operating on single-phase electricity.

This is the motor section only, allowing replacement of a compatible 4HP motor or assembly with a correctly selected Doyin borehole pump body.

Important Compatibility Note

The 3kW / 4HP specification is the motor’s drive rating. The final pump’s head, flow rate and water output depend on the pump body and impeller stages connected to it.

Always match this motor with a compatible 4-inch, 3kW / 4HP borehole pump body.

Installation Notes

• Confirm compatibility with the selected 4″ pump body
• Match the pump body to 3kW / 4HP
• Confirm adequate single-phase electrical supply
• Use correctly sized submersible cable
• Install appropriate motor and overload protection
• Ensure correct pump-body coupling
• Include dry-run protection where required
• Professional installation is recommended

Mini FAQ
